Cyborglandskap : landskapet, människan och teknologin

By using the cyborg as a structural tool to analyze certain aspects of human interaction with what can be perceived as landscape or landscape architectural elements, this thesis seeks to explore the concept of the cyborg landscape in order to place human practice in the context of postmodern ideas of the end of true nature. Ever since human kind has externalized evo-lution by using tools and extending the body with technological inventions, we have also taken our surroundings out of their natural trajectory. Everything we do that is conditioned by the use of technology is altering that which we perceive as nature and natural. Since we have been doing this for millennia we have of course also altered our surroundings by the influence of technology.This thesis uses three examples of landscape or landscape architectural elements that are conditioned by the integration of technology to explore this practice through a postmodern model of analysis based on the concept and basic premises of the cyborg, or the cybernetic organism. A cybernetic organism is in short an organism that has functioning technological parts integrated into its system.

Användarrelaterad energieffektivisering : En studie på länssjukhuset i Sundsvall

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.

Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

Energiaspekter på gestaltning : fallstudie Energihuset i Uppsala

This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.

En ?terinventering och analys av den svenska populationen av svart nervmossa (Campylopus atrovirens)

Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.

Småskalig biobränsleeldad kraftvärmeproduktion : teknik och investeringsutrymme

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

Mätning av implementeringen av lean inom sjukvård

The purpose of this thesis is to discuss how an instrument originally developed for measuring changes toward lean thinking inservice organizations in general should be adjusted in order to be of use in service organizations within the healthcare sector, andin hospital organizations in specific. The adjustments are suggested based on difficulties specifically arising when implementinglean within the healthcare sector.Thesis starting point is a pre-existing lean assessment instrument developed for service organizations in general. The thesis appliesa qualitative method and integrates literature from the health care sector and lean production movement with the expertise of tenacademics and practitioners in order to find difficulties associated with the implementation of lean within the healthcare sector.These difficulties then lie as the substratum for the adjustments suggested to be made on the instrument.The thesis finds that lean, as a philosophy, does not differ between service organizations in general and service organizationswithin healthcare settings. However, due to deficits in the general understanding of lean some adaptions on the instrument mustbe made. First, some words associated with production must be changed to words associated with healthcare.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Line–extensions; A longitudinal study concerning effects on brand equity

Thesis purpose The study aims to examine the effects vertical and horizontal line extensions might have on the total parent brand equity in terms of strength and its baseline product regarding of market share, loyalty and penetration under an elapsed period of time. The study aims to investigate a number of actual conducted line extensions effect on the above mentioned aspects of Kellers (1993) definition of brand strength as a part of the total brand equity. Methodology The effect of a number of line extensions of the parent brands and the baseline products is being examined in terms of market share, loyalty rate, cannibalization and market penetration. The thesis is focused on the correlations between these different parameters during a certain elapsed time ratio in order to test our theoretically routed hypothesizes in a deductive manner. Occasional correlations are derived from an indexation of data collected from the Gfk database. Theoretical perspective The study is derived from Kapferers (2004) definition of brand equity, where he is dividing the concept into three parts. This study is focused on Brand strength in particular, which is one of the parameters in the above-mentioned theory.

Outnyttjade resurser inom park- och naturvård

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Växthusvävens fukttransmission ? Hur struktur och materialval påverkar växthusvävens fuktgenomsläpplighet

Växthus används för att ge ett bättre odlingsklimat åt grödor och växter. För ytterligare förbättring av förhållandena används växthusvävar som exempelvis kan reglera temperatur, fuktighet och ljustillförsel. Väven som behandlas i denna rapport är en så kallad energiväv som främst har till uppgift att minska energiåtgången vid uppvärmning.När väven är fördragen nattetid, ökar luftfuktigheten då grödorna avger fukt dygnet runt. Fukten kan kondenseras mot energiväven, vilket gör att det bildas droppar på väven som kan falla ned på växtligheten. Den höga luftfuktigheten kan medföra svampsjukdomar och i övrigt också bidra till att tillväxten avstannar.

Vertikalt växthus : Ett gestaltningsförslag av växthus som bostadskomplement

Närproducerad odling är en trend som växer sig allt starkare och visar sig bland annat i form av stadsodlingar på tak och balkonger. Då det är begränsat med utrymme att odla på i städer är vertikala odlingar en alternativ lösning.I den här rapporten presenteras ett gestaltningsförslag av ett vertikalt växthus som ett bostadskomplement. Gestaltningen, byggtekniken och klimatet i växthuset är de områden som präglar dess form och tekniska lösningar.Växthuset har placerats på Haningeterrassen, ett bostadsområde under planeringför vilket olika skisser på kretsloppsanpassade växthus har tagits fram. Syftet var att ta fram ett förslag på hur ett växthus som bostadskomplement kan utformas, anpassas till platsen och bidra till en grönare stadsdel. Genom en platsanalys har ett lämpligt flerbostadshus valts som referenshus för projektet.Arbetet resulterade i ett förslag på ett vertikalt växthus som har kopplats till bostadshuset och ger de boende ett växthus i direkt anslutning till sin lägenhet.

Förfädernas berg? : en tolkning av fornborgen på Halleberg

The essay deals with the hill-fort on the mountain Halleberg, Sweden, its wall design, functionality, dating and its possible function as a central location and a place of worship of the ancestors.The Halleberg hill-fort consists of a 1500 meters long at times cohesive stonewalls which together blocked the mountain from its surroundings. Hallberg's natural vertical scree and cliffs along with the masonry blocked the whole mountain from the surroundings.The hill-forts, with few exceptions are largely not investigated archaeologically and its functionality and role in the ancient society is based on outdated research on the subject. The current archaeological interpretation is that hill-forts served as temporary defense in times of unrest or served as center of power for a social elite. The prevailing view in the archaeological sphere is that the hill-forts had a variety of functions and that its functionality and role in ancient society has varied.Halleberg´s strongest wall sections are at the mountain's south-eastern part where the natural driveway, Storgårdsklev is located. Along with the massive masonry of the walls in Bokedalen Storgårdsklev functioned as the hill-forts main entrance.
